Default HELP!! s2 RS TURBO MISFIRING

Rs turbo starts from cold without any misfire etc but as soon as it warms slightly approx 3-5 mins on tickover it starts misfiring poping / backfiring rough revving so far ive tried plugs, disconected cold start valve plug still same, then i tried another ecu, checked vac hoses, changed the coil, checked compression 120 psi on all 4 pots,
any ideas what it could be thats causing the missfire/backfire??

Bad fueling perhaps, check the CO.
